POCKET-DOOR FOR SCOWS AND HINGE THEREFOR.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed February 17, 1909. Serial No. 478,496.

To all 207mm it may concern:

Be it known that I, SYLvEsTEn GEORGE PERRY, of the town of Port Dalhousie, in the county of Lincoln, in the Province of Ontario, Canada, have invented certain new and useful Improvements in PocketDooi's for Scows and Hinges Therefor, of which the following is the specification.

My invention relates to ii'nprovemcnts in pocket doors for scows and hinges therefor, and the object of the invention to so construct and reinforce the door as to prevent wear and consequent leaking of sand also to provide a hinge which will allow of the door being quickly and readily removed for repairs and of a new hinge being supplied and it consists essentially of metallic end caps for the door, recesses formed in the caps on the hinge side of the door, such recesses being T-shaped in form and having supplemental recesses of a d-shaped form located to each side at the inside of the sa d recesses, edge strips having a rounded outer face extending between the caps along each edge of the door, hinge bars provided with laterally extending pins designed to fit into the d-shaped portion of the recesses, a chain connecting the said hinge bar with a portion of the side pocket of the scow as hereinafter more particularly described by the following specification.

Figure 1, is a general perspective view of the center or pocket portion of the scow. Fig. 2, is a cross sectional view taken through the pocket and scow. Fig. 3, is an enlarged perspective detail of the pocket door inter- Inediately broken away. Fig. 4, is a cross sectional view taken through the door and recesses thereof and one of the hinge bars. Fig. 5, is a sectional plan view of the hinge connection of the door. Fig. 6, is an enlarged perspective detail of one of the hinge bars.

In the drawings like characters of reference indicate corresponding parts in each figure.

A is the scow. A the pocket thereof provided with the usual inclined side portions A and vertical portions A.

B is my pocket door provided with a central body portion B preferably of wood, and metallic end cap portions B which fit on to the ends of the body portion of the door. The body portion B is provided with notches B at each end thereof and at the hinge side of the door. Such caps B are also suitably bolted to the ends of the door.

13 are edge strips which extend along each edge of the door between the end caps such edge strips being provided with rounded outer faces so as to allow of the free movement of the door in opening or closing.

The end caps B in their upper face are provided with the recesses T-shape in form. The stem of the T extending through the edge of the door at the hinge side.

B are supplemental recesses formed on each side of the inside of the T-shaped recesses B The recesses B are formed J- shaped for a purpose which will hereinafter appear.

C are hinge bars provided with a central bend C which extends over the angle formed by the junction of the inclined and vertical side of the pocket. The hinge bar C is also provided with laterally extending pins C which when in their position extend into the d-shaped portions B of the recesses 13'' as shown clearly in Figs. 4 and 5. The hinge bar is also provided. with an enlargement C which extends Vertically downward to support the hinge bar against the vertical side of the pocket.

D is a bracket secured to the inclined side of the pocket in roximity to the top thereof.

D are eyebo ts secured within the brackets and held on a line with the inclined side of the scow pocket. v

D is a chain connecting the eye-bolts l) with the inner end of the hinge bar (.7.

F are a pair of lugs which extend upwardly from each of the end caps B of the door B. These lugs are for the purpose of connecting the cable for operating the door, such cable extending upwardly over the pulleys 1, to suitable Windlass 2, or other operating means.

It is well known in doors of this class that when they have been in use for some little time they become worn particularly at the inner angles of the door where the doors contact together, such angle wearing away into a rounded form thereby leaving an opening which permits a great quantity of sand to leak through and consequently to a great extent minimizes the usefulness of the door. To overcome this I provide a reinforcing cap as above described which entirely obviates this and together with the edge strips forms an absolutely sand proof door. If one of the doors should become broken or otherwise injured it may be readily detached and entirely removed by slipping the laterally extending pins C of the hinge bar C out of the ends of the recesses B and up through the openings of the recesses B. In other constructions the hinge pin is located beneath thedoor and it is therefore almost impossible to remove the door when the scow is in the water. Also if the hinge itself should become broken it may be readily removed and a new one supplied. 7

From tnis description it will be seen that I have devised a very simple form of door and hinge therefor, such door being entirely sand proof and the hinge thereof being capable of being removed from the door with a minimum amount of time and labor and consequently with a minimum amount of expense.

What I claim as my invention is:

1. In a scow or dredge, the combination with the side walls of the pocket, and the door provided with T-shaped recesses extending through the hinge side of the door, of chains secured to the inclined sides of the pocket and a hinge bar secured to the lower ends of the chains and designed to have a hinge like engagement with the recesses of the door as and for the purpose specified.

2. In a dredge or scow the combination with the side walls of the pocket of the dredge or scow and the door, of metallic end caps for the door provided with a T-shaped recess extending through the inner face on the hinge side of the pocket, chains secured to the inclined sides of the pocket, a hinge bar secured to the lower end thereof, and hinge connecting means between the hinge bar and the recess formed in the pocket as and for the purpose specified.

3. In a device of the class described, a metallic end cap formed with a T-shaped recess in its upper face and extending through one side of the cap and Jshaped supplemental recesses formed to each side of the inside of the T-shaped recesses as and for the purpose specified.

4. In a dredge or scow, the combination with the side walls of the pocket and the door, of metallic end caps provided with T-shaped recesses extending through the upper face thereof and through the hinge side of the door, supplemental d-shaped recesses formed at each side of the inside of the T-shaped recesses, hinge bars provided with laterally extending pins designed to normally extend into the J-shaped portions of the recesses and a flexible connecting means connecting the upper end of the hinge bar with the inclined side of the scow as and for the purpose specified.

5. In a dredge or scow, the combination with the side walls of the pocket of the dredge, of end caps for the door provided with T-shaped recesses extending through the inner face and through the hinge side of the door, a J-shaped recess formed on each side of the T-shaped recess, a hinge bar provided with laterally extending pins at its lower end designed to fit within the J- shaped portion of the T-shaped recesses, brackets secured to the upper portion of the' inclined side of the pockets, eye-bolts extending through the brackets, and chains connecting the eye-bolts with the hinge bars as and for the purpose specified.

6. In a device of the class described, the combination with the door having T-shaped recesses provided with dshaped portions at each side thereof, of a hinge bar provided with laterally extending pins and designed to removably fit the inside of the d-shaped portions of the recess as and for the purpose specified.

7'. In a dredge or scow, the combination with the side walls of the door having vertical and inclined portions and the door provided with a T-shaped recess formed in its upper face and extending through the hinge side of the door, supplemental J-shaped recesses formed to each side of the T-shaped recess, hinge bars formed with a bend intermediately of their length designed to extend over the angle formed at the junction of the vertical and inclined sides of the pocket, laterally extending pins designed to fit within the d-shaped portion and recesses, a supplemental projection extending vertically downwardly and designed to normally bear against the vertical side wall of the pocket and a flexible connection between the upper end of the hinge bar and a suitable portion of the inclined side of the pocket as and for the purpose specified.
